Channel Measurement Reporting Quantities for Lower Signaling Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, the existing methods for configuring and reporting channel measurement resource sets result in high signaling overhead due to the need to report a large number of frequency domain basis vectors, especially when the system bandwidth exceeds 19, which complicates efficient communication.
Innovation Solution
A method and apparatus for indicating reporting quantities of channel measurement resource sets, allowing terminals to determine frequency domain basis vectors based on configured quantities, using a frequency domain window to reduce signaling overhead by selecting and reporting a subset of vectors, with network devices configuring different reporting quantities for different resource sets as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal reports all frequency domain basis vectors for channel measurement resource sets, then the measurement report completeness is improved, but the signaling overhead increases significantly
Solution Approach 1:
The patent extracts only the necessary frequency domain basis vectors from the complete set and reports them selectively. The network device configures channel measurement resource sets with specific reporting quantities, and the terminal reports only the required subset of basis vectors (e.g., first frequency domain basis vectors, second frequency domain basis vectors) rather than all possible vectors, thereby reducing signaling overhead while maintaining measurement report completeness for the configured resources
Solution Approach 2:
The patent applies different reporting quantities to different channel measurement resource sets based on their specific requirements. Instead of uniform reporting, the network device configures different reporting quantities for different resource sets (e.g., first reporting quantity for first resource set, second reporting quantity for second resource set), allowing each resource set to have the appropriate level of detail reported according to its local characteristics and needs
2Productivity
If the system bandwidth exceeds 19, then the communication capacity is improved, but the complexity of frequency domain basis vector reporting increases
Solution Approach 1:
The patent segments the frequency domain basis vectors into different groups (first frequency domain basis vectors, second frequency domain basis vectors, etc.) corresponding to different channel measurement resource sets. Each segment is reported separately with its own configured reporting quantity, which simplifies the reporting process for large bandwidth systems by breaking down the complex task of reporting all basis vectors into manageable portions
Solution Approach 2:
The patent introduces dynamic configuration of reporting quantities through network device signaling. The network device sends configuration information that dynamically specifies the reporting quantity for each channel measurement resource set, allowing the system to adapt the reporting complexity based on the actual communication needs and bandwidth conditions rather than using a fixed reporting mechanism

AI summary
Disclosed are a reporting number indication method and apparatus, and a storage medium. The method comprises: a terminal receiving configuration signaling, which is sent by a network device, wherein the configuration signaling is used for indicating a reporting number of a plurality of channel measurement resource sets, the plurality of channel measurement resource sets have the same reporting number, or, at least two of the plurality of channel measurement resource sets have different reporting numbers, and the reporting number is the number of frequency-domain basis vectors, which are reported by the terminal for the channel measurement resource sets, which correspond to the reporting number.
